A team of scientists from Weill Cornell Medicine and The Rockefeller University has illuminated the basic mechanism of Piezo proteins, which function as sensors in the body for mechanical stimuli such as touch, bladder fullness, and blood pressure. The discovery is a feat of basic science that also opens up many new paths of investigation […]

‘Organs in a dish’ pave the way for personalized medicine in gut and liver disease
One of the most exciting advancements in stem cell research has been the development of organoid systems, which are organ-like three-dimensional structures that mimic their corresponding organ in vivo. In this important review in Digestive and Liver Disease, published by Elsevier, scientists highlight some of the established and exciting novel uses for organoids or “organs […]
Allogeneic stem cell transplantation in non-Hodgkin lymphoma: Benefit remains unclear
The German Institute for Quality and Efficiency in Health Care (IQWiG) has investigated whether patients suffering from non-Hodgkin lymphoma have (better) chances of recovery when stem cells from another person are transplanted. In its final report now presented, the Institute concludes that it is not possible to make statements on the benefit of this high-risk […]
New ways to generate stem cells more efficiently
Induced pluripotent stem (iPS) cells are among the most important tools in modern biomedical research, leading to new and promising possibilities in precision medicine. To create them requires transforming a cell of one type, such as skin, into something of a blank slate, so it has the potential to become virtually any other kind of […]
Discovery casts doubt on cell surface organization models
Like planets, the body’s cell surfaces look smooth from a distance but hilly closer up. An article published in Communications Biology describes implications, unknown to date, of the way data from cell surfaces are normally interpreted; i.e. as if they lacked topographic features. When Earth is studied from space, its surface looks smooth, but on […]
A new molecular player involved in T cell activation
When bacteria or viruses enter the body, proteins on their surfaces are recognized and processed to activate T cells, white blood cells with critical roles in fighting infections. During T-cell activation, a molecular complex known as the microtubule-organizing center (MTOC) moves to a central location on the surface of the T-cell. Microtubules have several important […]
New, large sequence panel enables population genetics research in Africa
Geneticists have assembled the largest sets of African genomic data available to date, creating a resource that will help researchers understand the genetic structure of Africa as well as the effects of genetic variation on protein function and disease. The findings underscore the importance of including globally diverse participant cohorts in genetics research, and were […]
In apoptosis, cell death spreads through perpetuating waves
Inside a cell, death often occurs like the wave at a baseball game. What starts with two hands flung skyward prompts another, and another, until the wave has rippled far and wide across the whole stadium. This kind of a rolling surge, spurred by the activity of one or a few things, is known as […]
New lung cell type discovered: A previously unknown airway cell type may be a key to efforts to cure cystic fibrosis
In separate studies published online in Nature on Aug. 1, two independent research teams report the discovery of a new, rare type of cell in the human airway. These cells appear to be the primary source of activity of the CFTR gene, mutations to which cause cystic fibrosis, a multiorgan disease that affects more than […]
New method discovered to view proteins inside human cells: Scientists develop tagging device using Ferritin
Scientists at the University of Warwick have created a new way to view proteins that are inside human cells. Using Ferritin, a large protein shell that our cells use to store iron, the researchers have found a method they have called FerriTag that allows an electron microscope (EM) to view proteins precisely unlike current methods.
